ChatGPT Verification FAQs

Can I verify an OpenAI API developer account?

Yes, our non-VoIP numbers are fully eligible to activate OpenAI API keys and billing developer access.

Do I need a US IP / VPN for OpenAI?

Using a good quality US proxy or VPN during signup ensures OpenAI does not trigger geographical restriction warnings.

What if OpenAI says the number has too many accounts?

Simply cancel the number on USAVerify—you won't be charged—and click buy again to receive a fresh, unused number.

Why does OpenAI show the error: 'It seems you've provided a phone number from a VoIP service'?

OpenAI checks TeleSign and carrier type databases to block free virtual numbers (Google Voice, Skype, TextNow). USAVerify delivers real AT&T, Verizon, and T-Mobile physical SIM lines that OpenAI recognizes as legitimate cellular mobile phones.

Does this work for ChatGPT Plus and Claude AI registrations?

Yes, our numbers can be used across OpenAI ChatGPT Plus, API accounts, Claude by Anthropic, Perplexity Pro, and Midjourney accounts.
